Does enrollment extension mean Obamacare is in trouble?

The deadline for open enrollment for affordable health insurance has been extended, from March 31 to mid-April. Is this a sign that the president’s signature health care law is in trouble? The White House says no, that an anticipated surge in applications is the reason for the extension. But the law’s critics say it’s just another sign of the program’s problems. Insurers complain that it’s hard for them to calculate how much to charge customers if the rules keep changing. Connecticut’s exchange is standing firm on its March 31 deadline.
